Xantia dt engines?

[strictly_perv]

Think they have better heads and ceramic coated pistons, like the DHY. But that's only what I've read on here somewhere.

the only way to find out would be to take a xantia engine apart to see if theres any difference but tbh i cant see it been likely.
if you think about it, the xantia ran from 1992 to 2001, pretty much the same production run as the 306 and i just dont see citroen going to any effort to develop the xud engine further as that would mean massively increased costs per unit. not what you would be doing if you had joined up with peugeot to share components with the sole purpose of reducing production costs

Very fair point. If they had problems with melting heads ect then I might believe it but other than that why would they do it especially during the last few years of production when there's a new car lined up with new engines.
